Step-by-Step Guide to Fixing Klaviyo Email Template Issues
1. Check Klaviyo’s Email Template Editor for Errors
Errors in HTML, CSS, or Klaviyo’s drag-and-drop editor can cause display problems.
How to Check for Errors in Klaviyo:
Open Klaviyo Dashboard → Go to Campaigns or Flows.
Select the email template you want to fix.
Click Edit Template → Check for error messages in the right-side panel.
Solution:
If using custom HTML, make sure all tags are properly closed.
Remove any external CSS that conflicts with Klaviyo’s styling.
Use Klaviyo’s pre-built email blocks for better compatibility.
2. Use Klaviyo’s Mobile Preview to Ensure Responsiveness
Emails that look good on desktop may appear broken on mobile.
How to Check Mobile Responsiveness in Klaviyo:
In the Email Template Editor, click Preview.
Toggle between Desktop and Mobile views.
Look for misaligned text, oversized images, or cut-off content.
Solution:
Ensure text size is at least 14px for readability on mobile.
Set images to auto-fit width (max-width: 100%).
Use mobile-friendly layouts with stacked content.
3. Fix Email Rendering Issues for Outlook, Gmail, and Apple Mail
Emails can display differently in various email clients due to how each platform interprets HTML and CSS.
Common Display Issues in Different Email Clients:
Email Client | Common Issues | Fixes |
Outlook | Broken spacing, missing background images | Use tables instead of divs, avoid CSS floats |
Gmail | Line height inconsistencies | Use explicit line-height values (e.g., line-height: 1.5em) |
Apple Mail | Overlapping elements | Use fixed-width containers and test in multiple devices |
Solution:
Test across multiple email clients using Klaviyo’s Email Preview Tool or platforms like Litmus or Email on Acid.
Use inline CSS styles instead of external stylesheets.
Avoid complex layouts with multiple columns that may break.
4. Optimize Image Formatting and Loading Speed
Broken images or slow-loading graphics can affect email performance.
How to Fix Image Issues in Klaviyo:
Ensure images are JPEG or PNG format (avoid GIFs unless necessary).
Use web-optimized file sizes (below 200KB per image).
Check that image URLs are correct and publicly accessible.
Solution:
Resize images before uploading using tools like TinyPNG or Squoosh.
Use Klaviyo’s built-in image upload to avoid broken links.
Add alt text for accessibility and fallback support.
5. Adjust Margins, Padding, and Spacing for Better Alignment
Misaligned content or excessive spacing can make emails look unstructured.
How to Fix Alignment Issues in Klaviyo:
Click on the element (text block, image, or button).
Adjust Padding and Margin settings in the right panel.
Use grid layouts for better consistency.
Solution:
Keep consistent padding (10-20px) for readability.
Avoid negative margins, as they can break in Outlook.
6. Use Klaviyo’s Built-in Blocks Instead of Custom Code
Using external code can sometimes break Klaviyo’s email structure.
How to Use Klaviyo’s Built-in Email Blocks:
Open the Drag-and-Drop Editor.
Use pre-set blocks (Text, Image, Button, Divider).
Avoid pasting raw HTML unless necessary.
Solution:
If you need custom code, use Klaviyo’s Custom HTML Block but test before sending.
Stick to one-column layouts for mobile-first designs.
